WATER HEATER.

Application filed November 19,- 1923, Serial No. 675,739. RenewedAugust3, 1925.

To all whom it may concern:

Be it known that I, ELLIs- H. l/VILKINSON, a citizen of the' UnitedStates, residing at Bristol, in the county of Washington and State ofVirginia, have invented new and useful Improvements in Tater Heaters, ofwhich the following is a specification.

The object of this invention is to heat the water in a tank or reservoiremployed in connection with a cooking range or the like, by providingcirculation between the reservoir and a pipe extending through the lowerportion of the flue at the back of the range.

A further object is to avoid excessive heating of the water, whichfrequently occurs when a moderately hot fire is maintained and when thepipe providing for the circulation of the water extends into the fireboxor connects with a water back or water front in the fire box.

A still further object is to effect the desired result by direct andinexpensive construction, without change in the construction of thestove or range, beyond the provision of openings in the flue indicated,for the insertion ofcthe pipe.

With the foregoing and other objects in view, the invention consists inthe novel construction and arrangement ofelements described,illustrated, and claimed, it being understood that modifications may bemade within the scope of the claims without departing from the spirit ofthe invention.

In the drawings, Figure 1 is a View of a range in rear elevation, withmy improvement applied thereto; Figure 2 is a similar view of the range,with a portion of the rear smoke flue broken away to show a water pipeextending into this flue; Figure 3 is a View of the range in verticallongitudinal section, showing how the rear flue is subjected to indirectheat from the firebox; Figure 4: is a vertical section on a planeperpendicular to the plane ofFigure 3.

The flue of a range of a standard type is provided with the usual damper11 and opening 12 for connection with a smoke pipe leading to a chimney.The lower portion of flue 10 communicates with a chamber 13 under theoven 14, and the chamber 15 above the oven communicates with the firebox 16, and indirectly in the usual manner with lower chamber 18.

Openings are provided in the side wall of flue 10, below the damper, forthe pipe referred to below.

' A reservoir or tank 18 is positioned at the side of the range remotefrom the firebox, and pipes 19 and 20 extend respectively from the sideand bottom of the reservoir into the flue 10, where they are connectedby vertical pipe 21 and elbows 22, 23. Unions or couplings 2 1, 25, anddrain cock .26 serve the usual purpose.

This particular connection with the rear portion of the stove, andinvolving the flue carrying the products of combustion, has been foundespecially ffective, and the water is kept at an even temperature, nearthe boiling point, with a moderate fire.

What I claim is:

1. In adevice of the class described, a

firebox, an oven at one side thereof, a chamber extending around theoven and having communication with the firebox, a smoke flue 1ncommunlcatlon with the firebox and with the upper and lower portion ofthe chamber, a reservoir, and pipes extending from the reservoir andconnected therewith at different levels, said pipes extending into theflue, means in the flue connecting the pipes with each other, said meansextending upwardly alongside a vertical wall of the oven, and a damperfor diverting all products of combustion, from direct passage to theflue, into contact with the bottom, of the oven and thereafter aroundthe pipes in the, smoke flue. f

2. The combination with a range including an oven and firebox, of asmoke flue having permanent connection with the range at points aboveand below the oven, a reser voir, means for circulating water from thereservoir through the flue between said P0ints of connection, andmeans-for direct- I ing all products of combustion to the bottom of theovenand thereafter to said means for circulating water.

In testimony'whereof I affix my signature.

ELLIS HALE NVILKINSON.
